This app is designed to learn the correlation between respiratory variables [respiratory rate, tidal volume, dead space & fraction of inspired oxygen (FiO2)] and to know its impact on alveolar ventilation and blood gases.

ODC represents partial pressure of oxygen on horizontal axis and saturation of hemoglobin on vertical axis. The normal sigmoid curve can be shifted to right or left on the app. which indicates the decreased and increased affinity of hemoglobin to oxygen respectively.
